ABSTRACT:
Accidents occur
in various places. They are mainly grouped into two categories. They are those
that occur in cities and in rural areas. If an accident occurs in the vicinity
of a city or town, the accident victim is helped instantly by the people of the
locality whereas if it occurs in rural areas, the victim is helpless and his
fate is at serious risk. The victim has to be helped by those who pass by the
accident zone. The message has to be conveyed to the particular ambulance
service and it takes some time for the ambulance to reach the spot. It is this TIME FACTOR which claims the life of
the victim in minutes. The main problem is that they are not admitted to the
hospital in proper time. Hence, there is a great chance for the victim to loose
his life before he reaches the hospital. So to overcome this problem we design
an EMBEDDED SYSTEM, through which it
is possible to reduce the death rate caused by accidents (especially in rural
areas). The embedded system consists of three components. They are SENSORS, GPS SYSTEM, and GSM SYSTEM.
Sensors are used to sense the blood from the victim and to sense the damage of
the engine of the vehicle that has met with accident. Once the sensor senses
the blood and damage of the engine at the same time, the system that we discuss
over here finds the current location of the vehicle using GPS communication.
Then using the information perceived from the GPS satellite, it finds the NEAREST HOSPITAL and collects its
address and phone number. Once it finds, it stores those details in its
database. The GSM system fetches the phone number from database and sends the
voice coded message or SMS to the corresponding hospital using its phone
number. Then GSM system waits for some particular time to get an
acknowledgement from that hospital. If it does not receive any acknowledgement,
it requests the GPS satellite to find any other nearest hospital. GPS tracker
finds the details of that hospital and stores it again in database. Again the
GSM sends the same message to hospital and waits for some time. Once it
receives the acknowledgement from hospital, it stops requesting the GPS system
.This is the gist of the efficient accident detection system using 4-g
technology via embedded systems.
